Title: Paul Andrew Ringsrud: Innovator in Non-Contact Current Measurement

Introduction

Paul Andrew Ringsrud is a notable inventor based in Langley, WA (US), recognized for his contributions to the field of electrical measurement. With a total of seven patents to his name, Ringsrud has made significant advancements in non-contact current measurement technologies.

Latest Patents

One of his latest patents is a non-contact DC current measurement device with open loop degaussing. This innovative system provides a flexible current sensor capable of measuring current flowing through a conductor without direct contact. The design resembles a flexible loop of a Rogowski coil, but it is specifically engineered to sense direct current (DC). The current sensors utilize a novel open loop degaussing mechanism, which enhances the accuracy of DC current measurements. This is achieved through a current sensor that includes an AC degaussing coil wrapped around a magnetic core, driven by a circuit that resets the magnetic core for precise measurements.

Another significant patent involves systems and methods for placing an imaging tool in a test and measurement tool. This analysis system integrates a test and measurement tool that generates measurement data and an imaging tool that produces image data of a target scene. An electrical isolation mechanism is employed to protect the user from the test and measurement circuit, ensuring safety and accuracy during operation.
